When the Mothership jumps to South Carolina in 1863, the Time Team partners up with a courageous Union spy and military leader, Harriet Tubman - AKA "The General" - to thwart Rittenhouse's plan to alter the outcome of the Civil War. Back in the present, Rittenhouse hits the team where it hurts the most. Then, Jiya makes a daring escape from Rittenhouse that strands her in San Francisco's Chinatown in 1888 with no way home.
